Neural interfaces for somatosensory function restoration; Neural coding of sensation; Sensory learning; Psychosocial implications of artificial touch; Maximizing sensory information transmission using artificial intelligence

Dr. Graczyk’s research examines the coding and processing of somatosensory information and the perceptual and psychological experience of artificial sensation created by neurotechnology. She uses cross-disciplinary approaches to study sensation, including neural stimulation, computational modeling, psychometrics, behavioral assessments, and qualitative analyses. During her PhD training, she was awarded a National Science Foundation (NSF) Graduate Research Fellowship. She has recently secured independent funding from the Department of Defense and the Defense Advanced Research Projects Agency (DARPA) for her research projects. In 2018, Dr. Graczyk was named a DARPA Riser, one of a select group of early career investigators identified as potential future superstars whose work could impact national security.
